Yes they make very good foot gear for dogs with traction soles just like human climbing boots. My dog has them because the first time we went camping he cut up his paws bouldering with me. They cost about $40 and he has been using them for 4 years. If we are hiking he wears his booties.
We also have a harness for him if we have to use ropes.
We’ve turned back a few times when we decided the trail was too difficult to manage with the dog. I think this guy should have turned back long before he did in addition to the fact that he was not properly equipped.
YES! Kudos to you!
